A permutation F-test is performed, and a one-way analysis of variance F-test is performed.

response |
Numeric vector of responses if treatment is not |
treatment |
Vector of treatments, which need not be numerical.

num.sim |
The number of simulations performed.

The one-way analysis of variance F-test is performed, regardless of the value of num.sim
.
The permutation F-test is performed whenever num.sim
is at least 1.
The p-value of the permutation F-test is estimated by randomly generating the permutations,
and is hence not exact.
The larger the value of num.sim
the more precise the estimate of
the p-value of the permutation F-test, but also the greater the computing time.
Thus, the p-value of the permutation F-test is not based on asymptotic approximation.
The output consists of results from calling aov
and from the permutation F-test.
The formulas computed within perm.f.test
are based on the textbook by Higgins (2004).
